What are @datadog/browser-rum-core's main functionalities?

User Session Tracking

This feature allows you to track user sessions and capture key interactions and metrics. The provided code initializes the RUM monitoring with necessary configuration such as application ID and client token.

import { startRum } from '@datadog/browser-rum-core';

startRum({
  applicationId: 'YOUR_APP_ID',
  clientToken: 'YOUR_CLIENT_TOKEN',
  site: 'datadoghq.com',
  service: 'your-service-name',
  // Specify a version number to identify the deployed version of your application
  version: '1.0.0'
});

Error Tracking

This feature enables the tracking of errors that occur during a user's session. The code sample demonstrates how to manually log an error along with its severity level.

import { addError } from '@datadog/browser-rum-core';

addError(new Error('Something went wrong'), {
  context: {
    severity: 'error'
  }
});

Performance Monitoring

This feature helps in monitoring the performance of different views within your application. The code sample shows how to mark the start of a new view, which can be used to measure view load times and other related metrics.

import { startView } from '@datadog/browser-rum-core';

startView({ name: 'homepage' });
